Title: Mechanism for feeding workpieces
IPC: B23P19/00
Filed: 1979-11-23
Abstract: A mechanism for feeding workpieces such as screws, washers, nuts or the like to an automatic assembly machine in precisely timed relation with the operation of the machine includes a transfer finger 34 for feeding small workpieces, the transfer finger being pivotally mounted at the forward end of a rod 50 which is adapted to be advanced and retracted by a reciprocating pneumatic actuator 44. During the initial portions of the advance and retract strokes of the actuator, one or more radially contractible collets 52 frictionally grip the rod and prevent the rod from advancing and retracting the finger until such time as the actuator has pivoted the finger between active and inactive positions. <IMAGE>

Title: Improvements relating to bulk tanks
IPC: B65D90/02
Filed: 1979-12-10
Abstract: Bulk tanks for holding fluent substances, such as liquids, powdered and granular solids, are constructed from reinforced plastics materials by a method which utilises prefabricated reinforced plastics shell components 10, 20, 30 etc., which are assembled together to provide a tank of the desired size and configuration and the assembled shells are themselves utilised as a mandrel onto which additional reinforced plastics is laid up directly to connect and unitise the shells. The invention also concerns the basic shell components each of which comprises a side wall 11 defining an internal cavity and an end wall 12 extending across the cavity and integral with the side wall at one end thereof, as well as the final tanks. <IMAGE>
Patent GB-2071432-A (GB)
Title: Apparatus for Converting a Direct Input Voltage into an Alternating Output Voltage
IPC: H02M3/337
Filed: 1980-02-15
Abstract: The apparatus includes a push- pull inverter in which the pulse width of the pulse generator is variable and used for controlling the output voltage level when the alternating output voltage of the inverter is rectified. In order to avoid saturation of the main transformer 2, a two-winding current monitor transformer (3) is provided with its primary winding connected in series with the centre-tap of the main transformer, and the secondary winding is connected to a pulse width modulation control circuit 7 which varies the pulse width of the pulse generator and therefore the transformer duty cycle in response to the signal from the monitor transformer, the duty cycle of both halves of the transformer being reduced when the main transformer begins to saturate, this condition being signified by an abrupt rise in its primary current. In addition, current output overload of a d.c.-d.c. converter which includes a choke output filter is detected by employing a voltage comparator 17 to compare the voltage at the output port of the choke filter with an independently filtered voltage obtained at the input port of the choke filter, and arranging the voltage comparator to change its output level abruptly when the voltage level at the input port of the choke filter becomes higher than the output voltage level. The change in the output level of the voltage comparator is used to operate protective circuits. <IMAGE>

Patent GB-2062278-A (GB)
Title: Optical Fibre Connector
IPC: G02B6/38
Filed: 1980-09-12
Abstract: In an optical fibre connector component 5 including a tubular housing 10 and three round rods 14 supported longitudinally side by side within the tubular housing and defining between them an interstitial space 15 for reception of an optical fibre or optical fibres F, the tubular housing is of a material having a greater coefficient of thermal expansion than that of the material of the rods.

Title: Wave-powered orbital electrical generator
IPC: F03B13/20
Filed: 1981-09-10
Abstract: An electrical generator apparatus is provided for installation on a floating structure to extract useful energy from the action of waves on the structure. The apparatus comprises a weight 15 mounted for rotation about a vertical shaft 2 with its centre of gravity offset therefrom whereby any non-vertical motion of the floating structure causes orbital movement of the weight 15 about the shaft 2. Coupling means 18 serve to transmit movement of the weight 15 to the rotor 8 of the electrical generating part of the apparatus. These coupling means 18 may, for example, comprise a lost- motion coupling or an hydraulic circuit. Energy storage means can be provided to smooth the flow of energy from the orbital weight to the rotor 8. <IMAGE>

In the case of pin contacts, the contact area 16 of the pin portion 10 may be masked by the application of a sleeve 18: in the case of a socket contact, the internal contact area thereof may be masked by inserting a pin so as to become embraced by that area of the socket. <IMAGE>
Patent GB-2084300-A (GB)
Title: Faucet valve with diagonol o- ring seal
IPC: F16K5/04
Filed: 1981-09-21
Abstract: An improved faucet valve utilizes a static diagonal sealing ring 19 which coacts with a control member cylindrical flow control member 81 having a tapered lower end portion 95 in a relationship that provides substantially 180 degrees of control member rotation from full open to full close and vice versa, with metering of fluid flow taking place over a major portion of the control member rotational range. Contact is effected between nearly all of the sealing ring inner periphery with the control member flow control portion during initial opening and final closing stages when differential pressure is high, so there is no tendency for the sealing ring to be forced out of its grooves; the diagonal sealing ring does not move past a fluid discharge opening or vice versa, so the diagonal sealing ring is not subjected to chafing which would result in excessive wear. <IMAGE>

Title: Hydroponic cultivation system
Inventor: MORFOOT DAVID JOHN
IPC: A01G31/02
Filed: 1982-04-29
Abstract: In a hydroponic cultivation system, seeds to be germinated and/or grown are impregnated into blocks of chemically inert material. The blocks are porous and, when the base of each block is wetted by a stream containing nutrients, the wetting fluid is drawn up into the block by capillary attraction to convey the nutrients to the seed. Inert flint grit held together with a suitable binding agent may be used for the blocks. Each block may be netted, filmed, or otherwise prevented from decomposing too rapidly or from decomposing at all. A plug-in tray system enables individual trays with their blocks to be taken out of the overall system and replaced with other trays or used, once the seeds have reached a certain stage of growth, as an individual plant-rearing container. <IMAGE>
